Aluminum bolts are strong, lightweight, and commonly used in mechanical and electronic applications. They are ideal for outdoor use as they do not rust. Anodized aluminum bolts offer strength with minimal weight contribution and can be customized with color. Torque wrenches are often used to secure aluminum bolts without overtightening.
An aluminum bolt is a cylindrical fastener made of strong and lightweight aluminum metal. A narrow section on each aluminum bolt is usually partially or fully threaded with parallel slots. Aluminum bolts are commonly used to fasten parts in a wide variety of mechanical and electronic applications. The aluminum bolt is usually screwed into a threaded hole or secured with an aluminum nut on the protruding threaded end. Torque wrenches are sometimes used to precisely tighten aluminum bolts without causing them any damage.
Outdoor applications are the ideal place for aluminum bolts and nuts. Devices intended to regularly contact or be submerged in water are often connected with aluminum bolts. Aluminum does not rust in the presence of moisture like iron-based or ferrous metal bolts. Aluminum bolts, nuts and washers are available in a variety of sizes to replace less durable fasteners in a variety of projects. The slight increase in cost of an aluminum bolt is usually offset by its long life span.
Many aluminum bolts are anodized to give them color and seal them with a protective outer layer. An aluminum bolt is attached to a polarized electrical circuit such as the anode, or carrier of electric current. The anodizing process begins when electricity passes through the aluminum bolt and accelerates the oxidation of the surface. Aluminum does not flake and expose new vulnerable surfaces after oxidation like most iron alloys. The colored sealants adhere to the oxidized porous surface of the aluminum and actually strengthen the bolt.
Anodized aluminum bolts offer fixing strength with minimal weight contribution. Vehicles are able to run more efficiently as unnecessary weight is eliminated. Replacing the standard bolts with compatible aluminum versions can significantly reduce weight on aircraft, land vehicles and boats. Colored aluminum bolt sets can add a custom accent to a favorite piece of machinery. A properly installed aluminum bolt will last for years without the need for replacement.
Often a torque is used to secure an aluminum bolt without overtightening. Torque is a measure of the rotational force on an object. Many torque wrenches have a preset or adjustable torque setting to control bolt tightness. An ordinary ratchet or wrench can also be used to install aluminum bolts, but most commercial builders prefer the reliability of a torque wrench. Bolts are usually installed quickly by hand before a torque wrench is used to create even tension.
